Fig. 2 shows the indicative flowchart of the method 100 of regulation message transmission rate according to embodiments of the present invention, this method 100 can be performed by the device of regulation message transmission rate, the device can be single equipment, and be arranged in the transmission path of data；The device can also it is integrated in a base station, and be arranged in the transmission path of data.As shown in Fig. 2 this method 100 includes：

S110, obtains the resource scheduling information that base station is determined according to number of resources information, and the number of resources information indicates the number of resources that the base station can be dispatched.

S 120, receives the first frequency domain data transmitted with the first transmission rate.

S130, according to the resource scheduling information, Slow deposits the first frequency domain data of occupied Deta bearer unit carrying, and abandons the first frequency domain data of idle Deta bearer unit carrying.

S140, first frequency domain data deposited by Slow is transmitted with the second transmission rate, and wherein second transmission rate is less than first transmission rate. In order to while the business of communication system is not interrupted, message transmission rate can be adjusted, the device for adjusting message transmission rate can be when receiving the first frequency domain data of the first frequency domain data of upstream physical layer or down physical layer, the resource scheduling information determined according to base station based on number of resources information, the multiple Deta bearer units for being used to carry data for determining base station scheduling are occupied Deta bearer units, or idle Deta bearer unit, so as to which the device can cache the first frequency domain data of occupied Deta bearer unit carrying, and the first frequency domain data of the Deta bearer unit carrying of free time can be abandoned, so that the frequency domain data of transmission is reduced, so as to reduce message transmission rate.

Therefore, the method of the regulation message transmission rate of the embodiment of the present invention, by first caching the frequency domain data that occupied Deta bearer unit is carried, and abandon the frequency domain data of the Deta bearer unit carrying of free time, again with the frequency domain data buffered compared with low transmission rate transmission, it can avoid passing through deletion or newly-built community etc. changes system business caused by the method that the spectral bandwidth of system sets carrys out the transmission rate of change data and interrupted, thus, it is possible to adjust message transmission rate while keeping system business to proceed, to adapt to different data transmission conditions, so as to improve the transmission performance of system.

Specifically, in S 110, the device of regulation message transmission rate can obtain the resource scheduling information of base station determination first, the resource scheduling information can indicate scheduled Deta bearer unit, the status information of these scheduled Deta bearer units is also can indicate that, the status information can include seizure condition and idle condition.

It should be understood that in embodiments of the present invention, the device can obtain the resource scheduling information of base station determination in several ways, for example, the device can directly receive the resource scheduling information of base station transmission；The physical layer data that the device can also be reached by being resolved to, obtains resource scheduling information that base station is determined etc., but the present invention is not limited thereto.

It should also be understood that in embodiments of the present invention, the Deta bearer unit is the resource of carrying data, for example, the Deta bearer unit is RB, in another example, the Deta bearer unit is that but the present invention is not limited thereto by multiple RB user data cells formed etc..

In embodiments of the present invention, the resource scheduling information is that base station determines that the number of resources information indicates the number of resources that the base station can be dispatched, for example, number of resources that base station can be dispatched within the time of a time slot etc. according to number of resources information.

For example, based on LTE transmission agreement, the 20M corresponding RB of frequency language bandwidth quantity is that RB numbers workable for 100, i.e. base station scheduling are 100, base station needs to transmit 100 RB data within the time of a time slot.But the reasons such as the limitation due to message transmission rate, it is assumed that 50 RB data can only be transmitted within the time of a time slot, then RB numbers are by original workable for base station scheduling 100 drop to 50.

The number of resources information can be supplied to base station by other network equipments, for example, can be supplied to base station by network management device；The number of resources information can also be determined by the device of regulation message transmission rate according to message transmission rate information, and be supplied to base station.Specifically, as shown in figure 3, before the resource scheduling information that base station is determined according to number of resources information is obtained, this method 100 also includes：

S 150, obtains the message transmission rate information of data transmission channel.

S160, according to the message transmission rate information, determines the number of resources that the base station can be dispatched.

S170, the number of resources information is sent to the base station, and the number of resources information indicates the number of resources that the base station can be dispatched.

In S150, the device of regulation message transmission rate can obtain the message transmission rate information of data transmission channel.The message transmission rate information can for example include the message transmission rate information of each transmission channel, such as can include the maximum data transfer rate of each transmission channel；In another example, the message transmission rate information can include relatively minimal message transmission rate of transmission channel of peak transfer rate etc..

In S160, the device of regulation message transmission rate for example can determine the number of resources that the base station can be dispatched with 4 blunt message transmission rates and the corresponding relation of number of resources according to transmission channel.

Specifically, the blunt plural number for setting a physical layer RE data bit width as 16 bit real part bit wides and 16 bit imaginary part bit wides；One RB data volume is 84 RE data；One time slot is 0.5ms, then borrows the LTE system of bandwidth for 20M frequencies, it is necessary to complete the transmission of 100 RB data in 0.5ms seconds, that is, complete the transmission of 8400 RE data.Assuming that data are based on common public radio interface (Common Public Radio Interface, referred to as " CPRI ") agreement is transmitted, then can be according to the message transmission rate and the corresponding relation of number of resources of transmission channel, the number of resources that the base station can be dispatched is determined, the corresponding relation is, for example, following equation（ 1 ):

Wherein, N is the RB numbers that can be called in a time slot for N=(V*T)/(12*7*2*P*W) (1)；V is the message transmission rate based on CPRI agreements（Unit is bits per second）；T is the time of a time slot（Unit is the second）；P is the expense of CPRI host-host protocols（Such as bright use 8b/10b codings, then overhead value is 10/8*16/15);W is data bit width（Such as 16 bits）；Further, since the data in RE are plural number, and there are the data of two 16 bits of real and imaginary parts, therefore above-mentioned equation（1) denominator in also needs to be multiplied by the factor 2.

In S 170, the device of regulation message transmission rate can send the number of resources information to the base station, and the number of resources information indicates the number of resources that base station can be dispatched. It should be understood that in embodiments of the present invention, the device of regulation message transmission rate is also based on the other factorses such as data sampling mode and antenna number, determines the number of resources that base station can be dispatched, therefore the embodiment of the present invention is not limited to this.
